DRINK MIXER.

. Application filed February 25, 1922. Serial No. 539,059.

T 0 all whom it'wwy concern:

Be it known that l', RAYMOND B. GIL- CHRIST, a citizen of the UnitedStates, and a resident 'of Newark, in-the county, of Essex and State ofN cw Jersey, have invented certain new and useful Improvements in DrinkMixers, of which the following is a full, clear, and exact description.

The invention relates to drink mixers.

In machines for this purpose, the liquid constituents of the drink to bemixed are usually poured into a receptacle which is generally designateda shaker, from many different containers disposed away from the mixer.The receptacle with these constituents therein is brought to the mixerand placed in operative relation thereto and .is removed from themachine after each mixing operation, to discharge its contents. This isrendered necessary, because so many different ingredients and flavorsare used in making drinks that they are, in nearly all cases, mixedindividually. It is usually n'ec essary to run the agitator for aconsiderable period to properly blend or mix the constituentsand,,therefore, it is desirable that provision be made for retainin thereceptacle and agitator in operative re ation to permit the dispenser toperform other duties during the mixing operation. In drink-mix ing, itthus becomes necessary to frequently place the receptacle containing theconstituents into cooperatiue'relation to the agitator and to withdrawit from the machine to dis charge its contents and cleanse the recepthereceptacle in cooperative relation to the agitator, it has beennecessary in their use to manually manipulate the receptacle ntohoperative position and withdraw it there;

from and to additionally perform some sep-- arate step or operation,such. as lowering the motor and agitator together, or shifting theagitator and its shaft into the receptacle and relativelyto the motor,or raising and locking a receptacle-support to estabthe receptacle andagitator or to control the operation of the machine. Another desideratumin this art is to simplify the machine; by dispensing with movableconnections in and for the driving mechanism for the agitator. I

One object is to provide an improved motor-driven drink-mixer having anagitator which is mounted to work or rotate at a substantially fixedpoint with respect to the motor, with means adapted to receive thereceptacle and automatically retain the agita-tor and receptacle incooperative relation as a result of the manual manipulation or placementof the receptacle itself.

Another object is to provide a mixer of this character with automaticmeans for controlling the motor responsively to placement and removal ofthe receptacle.

A further. object of the invention is to provide improved means forremovably holding a receptacle in cooperative relation with the agitatoron a shaft depending from a stationarily supported electric motor.

A still further object is to provide improved means for controlling theoperation of the motor which drives the agitator.

Another object of the invention is to provide a machine which is simplein construction, which may be easily and readily operated and which isefficient in operation.

Other objects of the-invention will more fully appear from the followingdescription.

The invention consists in the several novel features hereinafter setforth and more particularly, defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a side elevation of machine embodyingtheinvention. Fig. 2 is a front elevation of the receptacle guide. Fig.3 is a vertical section. Fig. 4 is a section on line 4-4. of Fig. 3.Fig. 5 is a sect'ion on'line 5-5 of Fig. 3. Fig. 6 is a sec tion on line6-6 of Fig. 3.

The invention is exemplified in a machine comprising an electric motor10 f usual construction, to the rotor of which is secured ".a pendantshaft 11 with an agitator 12 fixed to its lower end; a hollow supportingstandard omprising a lower portion 13 fixed to a bottom member 14 whlchis secured to a base 15 by a screw 16, an upper member 17 suitablysecured in the member 13, and a lish and, maintain cooperative relationof bracket 18 suitably secured to the upper end.

' of member 17 to which the motor is suit 23,connected to the motor and,normally. disconnected switch-members 24 and 25 included in theconductor 23 to control the operation of the motor. The casing of themotor 10 is fixedly secured to the support at 19 and the agitator 12 ismaintained in substantially relatively fixed vertical relation to themotor.

A receptacle 26 having an open top, a closed bottom 27, a lowerwear-band 28 and an upper wear-band 29, is adapted to .contain theconstituents of the drink tobe mixed and to be placed into cooperativerelation to the agitator from beneath the latter, which is supportedsufliciently above the base 15 and away from the receptacle-supporthereinafter set forth to permit the insertion and withdrawal of thereceptacle. I

The invention contemplates placement of the receptacle into and out ofoperative relation to the agitator, locking and unlocking the receptacleand control of the motor by manipulation of the receptacle itself, sothat shift of the motor or the agitator are not necessary to bring theagitator into working position in the receptacle. For this purpose, astationary vertically extending receptacle-guide is provided for theback of the receptacle and comprises a lower inclined or upwardly andbackwardly sloping member or portion 30 and a vertical upper portion 31with a supporting-ledge 32 between'them. The guide has its front facecurved or arcuate in substantial conformity with the outer periphery ofthe receptacle so that when the latter is pressed backwardly against theguide, the receptacle will be guided against lateral movement and intoits operative position without danger of striking the agitator 12.

he receptacle is adapted to be removably' and securely held in operativeposition by the ledge 32 which has an inclined rearward- 13' anddownwardly extgiding surface 32 to efiect the lower portion ofthereceptacle backwardly against the front face of the guide-member 31 andhook 33 which is adapted, in conjunction with said member, to hold theupper portion of the receptacle against lateral movement in anydirection,

being extended into the receptacle to engage its inner-periphery forthis purpose.

y causing the abutment or holding member 33 to confine the upper andrear portion of the receptacle, the weight f the front portion of thereceptacle and the material therein will tend to hold the lower portionof the receptacle in its seat on ledge 32 and against guide-member 31.Hook 33 is secured by screws 33 to a strip 13' and guide 31 is providedwith lugs31 which are also secured to strip 13*. The latter is securedto the supporting standard by screws 13*.

For the purpose of automatically controlling the operation of the motorbymanipulation of the receptacle, a switch-lever 34 has its lower end 35formed to pivotally fit in the lower end of the standard-member 13 andon the plate 14, is extended through a slot 36 in front ofthesupporting-standard and through a slot 37 formed in guidemember 31and is provided with a camportion 38 which is adapted to be struck bythe receptacle 26 while it is being raised into operative position andto beheld in shifted position as long as the receptacle remains in itsoperative position. A stop-shoulder 34 is provided on lever 34 to limitthe forward movement of the lever under the influence of spring 43, soit will be normally projected into the path of the receptacle thecorrect distance to operate the motorswitch. Lever 34 is also formedwith a cam 39 in the hollow standard, to shift and control a plunger .40which is slidably held in the hollow-standard and carries a switchpin 41at its upper end which is adapted to bridge the gap between the normallyseparated switch-members 24 and 25 and close insulating material 44suitably held in the upper end of the standard-member 17. "A wear-plate45 is secured to the lower end of plunger 40. y

The operation of the machine will be as follows: Assuming the parts tobe in normal position shown in Fig. 1, the operator will placereceptacle 26 containing the constituents of the drink to be mixed,against inclined guide-member 30 and under the agitator 12 as shown bydotted lines in Fig. 1, press it rearwardly with sufficient force tocause the guide to laterally control its vertical movement, and thenlift it. In this manipulation, the receptacle will slide on thefront-face of the receptacle-guide.

After the receptacle leaves the inclined guide-member 30, it will bearagainst the vertical guide-member 31 and be raised until that the cam 39will raisethe plunger 40,

cause the pin-41 to bridge the switch-members 24, 25 and close thecircuit for the operation of the motor 10 and cause it to drive theagitator. This occurs preferably before the receptacle reachesitsoperative position so that the agitator willbe rotating and bore its waythrough any hard material, such as ice cream, as the receptacle is beinglifted. The hook or holder 33 positively holds the upper portion of thereceptacle, so that it will not be displaced by the forward pressure ofthe switch lever 34 which isunderjhe influence of spring 43 which tendsto hold the switch-lever normally in the position shown in Fig. .2 andto hold the receptacle. When the motor has run for the desired periodand the mixing operation has been completed, the operator will raise thereceptacle 26 sufliciently to cause it to clear the inclined surface 32of ledge 32 and tilt the lower portion of the.

receptacle forwardly a short distance to cause its lower back portion toclear, and be released from, the ledge. Thereafter, the operator willlower the receptacle and press it backwardly sufficiently so that thereceptacle will follow the path controlled by guide-members 31 and 32.The wear-band 29 is of sufficient height to prevent its lower edge fromcatching on ledge 32 while the receptacle is being lowered. When thereceptacle has been lowered sufliciently to clear the agitator 12, itwill be withdrawn forwardly away from guide-member 30. During thelowering of the receptacle, the switch-lever 34 will pass into itsnormal position to release plunger 40 and cause it to break the circuitand stop the motor. This occurs, preferably, after the vessel has beenlowered sufficiently to bring the liquid therein below the agitator sothe latter will'run for a suflicient period to discharge the adherentliquid by centrifugal force into the receptacle.

In the drink-mixers comprising an electric-motor with an agitatorattached to its rotor, a high speed, usually ranging from 5,000 to14.000 revolutions per minute, is attained, and when a receptacle orcontainer which issubstantially circular in cross-section,'asillustrated in the drawings, is used, the agitator. if operatingconcentrlcally 1n the receptacle, will rotate the entire contents orliquid in the receptacle at a high speed and produce a vortex in thematerial. By retarding the rotation of the contents to cause greaterrelative rotation of the agitator and latter will pass into or nearlyinto concentric relation to the receptacle and then produce or increasethe vortex. This is of advantage, because during the withdrawal of thereceptacle, the vortex will cause the liquid to clear the agitatorsufliciently early to cause the agitator to centrifugally cleanse itselfby discharging the adherent particles into the receptacle before thelatter is completely withdrawn.

The axis of the receptacle while it is in its operative position, isdisposed between the agitator and the supporting column. Acharacteristic advantage of this arrangement is that it providesadditional clearance for the receptacle in itsplacement into and itsremoval from its operative position.

The invention exemplifies a motor-driven drink-mixer with an agitatorcarried in substantially fixed relation to the motor; in which manualmanipulation of the receptacle itself, results in bringing it and theagitator into and in automatically retaining them, incooperativerelation; in which manual ma nipulation of the receptacleitself results in automatically retaining it and the agitator incooperative relation and in automatically controlling the motor; inwhich the receptacle-holding -means and the agitator are normally andco-relatively positioned with clearance to permit the receptacle to bereadily placed into and withdrawn from its operative position; in'whichplacement and securing of .the receptacle in its holding-means areaccomplished by manually shifting the receptacle itself backwardly andupwardly around the agitator to its point of deposit, in which the motorand agitator are statio11- arily mounted and the receptacle-holdingmeans is disposed entirely at the rear of the agitator'to providereceptacle-clearance between the support and the agitator; in which asubstantially stationary receptacle-support is used with a stationarilymounted agitator; in which the switch for the motor isreceptacle-controlled and closed in advance ofthe time when thereceptacle passes into its fixed operative position; in which saidswitch is opened after the receptacle has been partly lowered from itsfixed position; in which the receptacle is well guided in its placement1 and removal; in which the agitator operates eccentrically while thereceptacle is'retained and concentrically during its withdrawal; inwhich the receptacle holding means is simple in construction; and bywhich the steps to be performed by the dispenser are simpli fied andreduced to the minimum and the service expeditedand improved. I
